Anyway, I'll try to keep this brief since the story isn't much explained in this sequel and I hope the sequel in July will clear up a lot of stuff.
Story 7/10:
If I were to summarize it, I would say it involves the Yakuza, some other gang members joining the Dollars, some assassination attempts, kidnapping and new enemies and friends.
The sequel elevates to a new level of gang warfare. It's on a much bigger scale and involves some big mafia groups. The Dollars are again in trouble and this time it's too big to control within Ikebukuro and it brings gangs from other towns to beat the Dollars up.
One story is that of the Dollars getting beat up by a gang from another town. This one involves Mikado, Kadota, Anri and some new characters.
Another story is about Celty, some Russian assassins, a kidnapped girl and the Yakuza.
These both stories do intertwine as is expected of the Durarara series. At first, it may become a bit confusing with all the new names and groups but halfway down the series, you'll begin to understand what happened. Though some characters who play a key role in the series don't get much attention which may cause you to forget about them but it's still all okay considering it will get a sequel.
Art 8/10:
The art and animation just like the prequel, is the same. It's good. Not much to say about it since you know what's it like.
Sound 8/10:
The ending is "Never Say Never" by Three Lights Down Kings. The ending video is in the same style as it was in the prequels first ending "Trust Me". Anyway, the song is pretty good. As for the opening, I'm not that big a fan of it.
Characters 8/10:
Many new characters are introduced in the series but the downside is the insanely low screen time they get. The old characters still remain but some of them get less screen time since they are no longer in Ikebukuro (Kida Masaomi).
The new characters include 3 juniors of Anri and Mikado, a new gang and their boss, the Yakuza (old and new), Russian assassins, a new superpowered character.
Two of them are Izaya's little twin sisters who, in my opinion, are awesome. They are twins, but with opposite personalities. They have the same sort of combat/athletic skills like Izaya and can stand on their own in a tough situation. They are also pretty comedic and fun to watch. Not to mention really cute. But they get really less screen time which didn't make me happy.
The other junior is Aoba who I won't explain much as it may spoil. But, in short terms, he's a junior who looks up to Mikado.
Then comes Hijiribe Ruri, who is also insanely cute but gets less screen time. Again, won't go into details.
Backstories of some new characters is told. Though it doesn't have much importance. As for romance, there are slight hints but it doesn't get much progress.
Some of the new characters, though thought to be the main cast, aren't that important and the series pushes them to the sidelines after a few episodes. Only a few of the new characters really remain till the end of the sequel. But I hope the others get some mention in the sequel coming this July.
Enjoyment 8/10:
Really enjoyable. Even more so than the prequel. Maybe because it was a bit fast and had some new characters and more fights. Although most stuff took some time to understand but still it was enjoyable once you know who is who and which groups works for who.
Overall, it's a pretty nice sequel. And the fact it gets another sequel is the only reason I refrained from scoring it any lower because no matter how you look at it, this story can't be explained in 12 episodes only.
And a heads up, do remember the members and which group they belong to, especially for the Yakuza since that is important in understanding the story.
